| 摘 要： | 利用辽宁大连的紫贻贝(Mytilus galloprovincialis)与福建宁德的厚壳贻贝(M.coruscus)为亲本,采用2×2双列杂交设计,构建了紫贻贝自交组(M.galloprovincialis♀×M.galloprovincialis♂)、正交组(M.galloprovincialis♀×M.coruscus♂)、反交组(M.coruscus♀×M.galloprovincialis♂)与厚壳贻贝自交组(M.coruscus♀×M.coruscus♂)4个遗传组合,比较分析了受精率、孵化率、子代的成活率、生长数据等,探讨了紫贻贝与厚壳贻贝种间杂交的可行性,同时为贻贝良种选育提供参考。结果表明,自交组与反交组的受精强度具有不对称性,正交组与自交组受精率无差异,反交组的受精率及孵化率显著低于正交组与自交组(P0.05),且浮游幼虫不能正常存活;正交组子代具有生长优势,第9、11、13天的浮游幼虫及第78天的稚贝壳长均显著大于自交组(P0.05);正交组与紫贻贝自交组在整个幼虫阶段存活率无显著差异,在壳顶幼虫期显著高于厚壳贻贝自交组(P0.05)。
